Psychopathology Flashcards
what are the 4 definitions of abnormality?
- statistical infrequency
- deviation from social norms
- failure to function adequately
- deviation from the ideal mental health
what is statistical infrequency?
- a persons trait, thinking or behaviour is abnormal or statistically unusual.
- eg: IQ
what are the strengths of statistical infrequency?
STRENGTHS
-This definition can provide an objective way, based on data, to define abnormality if an agreed cut-off point can be identified
WEAKNESSES
- Statistically speaking, many very gifted individuals could be classified as ‘abnormal’ using this definition. The use of the term ‘abnormal’ in this context would not be appropriate
what is deviation from social norms?
-A person’s thinking or behaviour is classified as abnormal if it violates the (unwritten) rules about what is expected or acceptable behaviour in a particular social group
what is the strengths of deviation from social norms?
-This definition gives a social dimension to the idea of abnormality, which offers an alternative to the ‘sick in the head’ individual
what are the weaknesses of deviation from social norms?
- cultural differences
- norms can vary over time.
what is failure to function adequately?
-Failure to function adequately (FFA) refers to abnormality that prevent the person from carrying out the range of behaviours that society would expect from them, such as getting out of bed each day, holding down a job, and conducting successful relationships etc
what are the strengths of failure to function adequately?
-provides a checklist
what are the weaknesses of failure to function adequately?
- Failure to keep a job may be due to the economic situation
- cultural differences
what is deviation from ideal mental health?
Jahoda suggested six criteria necessary for ideal mental health. An absence of any of these characteristics indicate individuals as being abnormal, in other words displaying deviation from ideal mental health.
Resistance to stress: Having effective coping strategies and being able to cope with everyday anxiety provoking situations.
Growth, development or self-actualisation: Experiencing personal growth and becoming everything one is capable of becoming.
High self-esteem and a strong sense of identity: Having self-respect and a positive self-concept.
Autonomy: Being independent, self-reliant and being able to make personal decisions.
Accurate perception of reality: Having an objective and realistic view of the world.
what are the limitations of deviations from the ideal mental health?
- people don’t meet all criteria
- cultural differences.
what are the characteristics of OCD?
COGNITIVE
- what do you think?
- reoccurring thoughts
EMOTIONAL
- how do you feel?
- obsessive thoughts often lead to anxiety, worry and distress
BEHAVIOURAL
- how do you behave?
- compulsions
- the need to complete a specific action/routine
what does the genetic explanation of OCD suggest?
-it is polygenic
-family + twin studies
-the serotonin transporter seems t be mutated in OCD patients
this leads to an increase in the reuptake of serotonin
what is the evaluation for the genetic explanation of OCD?
- Carey and Gottesman (1981) found that identical twins showed a concordance rate of 87% for obsessive symptoms and features compared to 47% in fraternal twins. This difference suggests that genetic factors are moderately important.
- stress diathesis model? genes on their own may now solely cause OCD
- imitate behaviour not due to genetics
what does the neural explanation say about OCD?
- the prefrontal cortex is involved in decision making and the regulation of behaviour.
- overactive PFC causes an exaggerated control of behaviour.
- serotonin is thought to be involved in the regulation of mood.
- OCD patients have a low level of serotonin
